3.5 Select the irrigation temperature

If the Aqua Stim is used as a stand-alone device, press the front panel "Cool" button to select the Cool
Irrigation or press the front panel "Warm" button to select the Warm Irrigation. The irrigator display will
show when the irrigator is ready for irrigation.

3.6 Set the irrigation time

The Aqua Stim default irrigation time is 30 seconds. Using the Aqua Stim default flow setting (500 ml/min)
the irrigation volume is 250ml. For the current irrigation, the duration can be reduced from 30 seconds to
a minimum of 15 seconds using the front panel up & down "TIME" push buttons. Changing the irrigation
duration will also change the irrigation volume.

3.7 Perform the Irrigation

Prior to irrigation, the patient should be supine with their head elevated 30 degrees. The patient's head
should be at an elevation within 12 inches / 30 cm (higher or lower) relative to the irrigator height.
Irrigating with the patient elevation too high or too low could adversely affect the irrigation flow rate.
NOTICE
Once the selected irrigation temperature has been reached, the irrigator will beep and say "Ready". The
LEDs in the handle will also light up. Place the irrigator tip gently into the ear canal, then click the button
on the irrigator handle to begin water flow and the VNG/ENG software will begin recording. Direct the
water at the ear drum. Catch the water in an emesis basin placed below the ear as it drains from the ear
canal. After each irrigation, properly dispose of this contaminated water.
If the irrigation needs to be suddenly aborted, remove the tip from the ear and direct flow into the emesis
basin. Press and hold the button on the irrigator handle for 2 seconds. The irrigator will beep, stop the
water flow, and display the standby idle screen.
Ten seconds after the irrigation is complete, water will be pumped from the external tank to get ready for
the next irrigation. The display will read "Filling..." during this operation.
Once the final irrigations have been completed, remove the silicone tip and clean the handle tip with Sani-
Cloth wipes.

An audiologist or physician should inspect the patient's ear with an otoscope
prior to testing, looking for infection, open wounds, wax impaction, or a
perforated eardrum. If any of these are observed, DO NOT use the Aqua Stim.
The purpose of a caloric irrigation is to cause a temperature imbalance
between the left and right ear. The irrigation of a functional ear will result in the
patient feeling like the patient is spinning for a minute or two after the irrigation
is over. This is normal. However, some motion sensitive patients may
experience nausea. The examiner should be prepared for some patients who
vomit as a result of the irrigation. Do not perform any more irrigations during
this visit if the patient vomits.
Irrigation using the handle button is done by the "press and hold" method or the
"push and release" method. The irrigation will continue for the predefined
duration even if the button is released from "press and hold".
